Flood warnings that arrive before the water does.

Neerova builds urban flood early warning systems for Indian cities — sensors in the drains, a calibrated model of the network underneath, and alerts that reach the people who can act while there is still time to act.

Neerova.ai and FloodCtrl, our flood early warning and decision support platform, go live on 15 October 2026. Until then, write to us — we're in conversation with cities planning for the next monsoon.

Inside an urban flood early warning system

FloodCtrl is one chain, end to end: from a rain gauge tipping in a ward to a pump starting and a message on a duty officer's phone.

Sense

Ultrasonic level sensors in drains and sumps, tipping-bucket rain gauges and pump telemetry, reporting every minute over cellular with a long-range radio fallback for when the network gives out.

Forecast

LiDAR terrain and DGPS-surveyed stormwater drain networks feed hydrological and hydraulic (H&H) models, so rainfall becomes predicted depth at a known junction, not a general warning for the city.

Warn

Thresholds escalate from watch to alert. Each step has a named recipient, a channel and an action already agreed with the city — CAP-compliant SMS and WhatsApp, public address sirens, dashboards, control room.

Act

A decision support system for the city's flood cell and integrated command centre: SCADA pump and dewatering status, hotspot depths, evacuation triggers, and a record of what was decided and when.
